ANALYSIS OF SLOPE STABILITY FOR THE SLOPE CUTTING OF KENDRIYA VIDYALAYA PLAYGROUND, AIZAWL, MIZORAM

Slope stability problem had never been solved completely and will never be because a slope has a natural tendency to fail. In most applications, the primary purpose of slope stability analysis is to contribute to the safe and economic design of excavation embankments, earth dams, landfills and spoil heaps. In this case, stability of soil on a hilly terrain is checked to know whether a level surface for playground can be made out or not. When dealing with slope in general and slope stability analysis in particular, geological and geotechnical experience in an area is valuable. In this study the properties of the soil by various types of soil test has been determined using specific gravity, liquid limit, plastic limit, moisture content, dry density, permeability and parameters such as cohesion (C) and angle of internal friction (i). By knowing the parameters of the soil, slope/w analysis were performed using Morgenstern Price Method and factor of safety was determined for different height and with different inclined angle. It has been found that the hill side slope cutting has a factor of safety at the height of upto 14 m, with slope angle of 32.47 0 .
